Bootcamp creates the partitions OK and it seems to copy the Windows Install files OK but fails when trying to copy the Bootcamp support files. I have decided to go for a more hardcore approach. I've tried the smaller ISO with Bootcamp and it still fails. Using the media creation tool that Win7 downloaded rather than the on-line media creation tool via a browser I have downloaded another copy of the 64 bit ISO and this one is 4.1GB while the one done via the browser method was 4.7GB, very odd.
When I opened the Disk Utility app to remove the Bootcamp partitions I noticed that t had formatted it to 80GB even though I'd left it set to 56GB so there's definitely something odd going on.Īny help sorting this out would be greatly appreciated.
When I start bootcamp it suggests a windows partition size of 56GB which I then increase to 80GB, on my last attempt I decided to leave it at the suggested size of 56GB bootcamp fails in exactly the same way. I can remove the Bootcamp partitions and revert to OSX only. I've tried several supposed fixes thrown up by a Google search but nothing works. It then fails saying that the Windows Support software could not be saved to the selected drive. I opted for an 80GB partition and Boot Camp creates this then downloads the Windows Support Files and copies the files across from the ISO. I have downloaded the 64 bit ISO - Win10_1803_English_圆4 which is under 5GB so should work. I need a working Win10 installation but can't get Boot Camp to install it on my iMac (Retina 5K, 27-inch, Late 2015).
